Bill (AKA glueguy), Thanks man, I don't know when or if ever that simple tip would have occurred to me! Run a tap down it and make a good set of threads, just farther down. Like du-uh... I got no problem with glueing in the right place if it would hold but prefer your tap idea (or both), I F I can get a tap in to it and turn it, its in a pretty hard to get to place but when I get my tractor back from service (they came for it at lunch today and already I'm in withdrawal and suffering separation anxiety) I'll give it a try.
